I agree with what Octane said, replacing the batteries in the modern electronics is a lot harder, but curiously with the video game controls it is still easy if you have the cheap tools to remove a few screws....

Xenoblade 2 and Zelda BOTW are my top picks!
And i'm waiting for Smash like all of us right!?
Some tips:
- If you have any other controller buy a Magic NS or 8bitdo adapter to use it with your switch (Only one controller for each adapter)
- Some games looks the same and feels a lot better when you put the TV output to 720p.
- If you buy third party Docks, only use good brand USB C cables
